一、问题简介
- Mac Homebrew 安装与卸载
- 有时候在
brew update、brew install xxx… 命令的时候会长时间没反应或者卡在Updating Homebrew...。 - 原因是：由于我们安装的
brew默认repo是官方的repo，出于国内特殊原因无法连接，所以使用Alibaba的Homebrew镜像源进行加速后问题就能解决。 - 平时我们执行
brew命令安装软件的时候，跟下面3个仓库地址有关：
brew.git homebrew-core.git homebrew-bottles
二、解决办法（按步骤依次替换下去，后续可还原）
$ cd "$(brew --repo)" $ git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
- 还原：
$ cd "$(brew --repo)" $ git remote set-url origin https://github.com/Homebrew/brew.git
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" $ git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
- 还原：
$ cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" $ git remote set-url origin https://github.com/Homebrew/homebrew-core.git
$ echo $SHELL 会输出 /bin/zsh 或 /bin/bash
- 2、如果输出
/bin/zsh，访问地址换成这个:
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.zshrc $ source ~/.zshrc
- 还原：
$ vi ~/.zshrc # 然后，删除 HOMEBREW_BOTTLE_DOMAIN 这一行配置 $ source ~/.zshrc
- 3、如果输出
/bin/bash，访问地址换成这个:
$ echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.bash_profile $ source ~/.bash_profile
- 还原：
$ vi ~/.bash_profile # 然后，删除 HOMEBREW_BOTTLE_DOMAIN 这一行配置 $ source ~/.bash_profile
$ brew update
$ brew doctor # 输出如下的错误信息 /usr/local/Homebrew/Library/Homebrew/global.rb:12:in `require': cannot load such file -- active_support/core_ext/object/blank (LoadError) from /usr/local/Homebrew/Library/Homebrew/global.rb:12:in `<top (required)>' from /usr/local/Homebrew/Library/Homebrew/brew.rb:23:in `require_relative' from /usr/local/Homebrew/Library/Homebrew/brew.rb:23:in `<main>'
- 无论报什么错误，先不管，执行以下命令
$ brew update-reset
- 等待更新完成之后，再次执行
$ brew update
Error: homebrew-core is a shallow clone. To `brew update`, first run: git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow This command may take a few minutes to run due to the large size of the repository. This restriction has been made on GitHub's request because updating shallow clones is an extremely expensive operation due to the tree layout and traffic of Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you automatically to avoid repeatedly performing an expensive unshallow operation in CI systems (which should instead be fixed to not use shallow clones). Sorry for the inconvenience!
- 删除
homebrew-core后更新即可
$ cd /usr/local/Homebrew/Library/Taps/homebrew $ rm -rf homebrew-core $ brew upgrade
// 进入 Taps 文件夹 $ cd /usr/local/Homebrew/Library/Taps // 新建 homebrew 文件并进入，如果有这个文件可以直接进入 $ mkdir homebrew && cd homebrew 或 $ cd homebrew // Git 下载 $ git clone git://mirrors.ustc.edu.cn/homebrew-core.git
- 成功之后，执行安装命令，中途需要回车确认:
$ /bin/bash -c "$(curl -fsSL https://cdn.jsdelivr.net/gh/ineo6/homebrew-install/install.sh)"
- 最后看到
==> Installation successful!就说明安装成功了。
最后可以在更新一下，一般现在已经是最新版本了，然后就可以通过brew进行安装工具了。
$ brew update
- 基本到这就搞定了！！！配置完后再去安装下某些工具和
module时就能发现畅快无比了！！
